Chapter III.— SYNOPSIS OF ZOOLOGICAL DATA. 

 I. THE DREDGING RECORDS. 



Complete records were kept of every dredge haul of the Survey, comprising such 

 data as the bearings, date, depth, etc., at each station, as well as a list of the aggregate 

 fauna and flora found to occur there. It was our original expectation to publish the entire 

 set of station records as an appendix to the present report, for it would certainly be 

 desirable to insure the permanency of these records through printing. They are the 

 crude data upon which most of our ensuing discussion is based, and it is highly probable 

 that they would yield other results of value if subjected to further analysis. Here, 

 and here only, do we find what forms of life are associated together upon a given 

 area of the sea bottom. Owing to the voluminous character of these records, however, 

 it has not been found practicable to publish them in their entirety, although a "List 

 of Stations" is presented at the close of section I. As regards the associations of 

 species, we must be content at present with presenting the data in a generalized form, 

 except for the reproduction of a very few complete station records by way of illustration. 



In all there are 458 stations, belonging to the regular series, which may be classi- 

 fied as follows: 



Fish Hawk, Vineyard Sound 218 



Fish Hawk, Buzzards Bay 66 



Fish Hawk, Crab Ledge 7 



Phalarope and Blue Wing, Vineyard Sound 77 



Phalarope, Buzzards Bay 90 



Total 458 



With a few exceptions (see below) these stations were all dredged during the sum- 

 mers of 1903, 1904, and 1905. The Fish Hawk was employed during all three of these 

 seasons, the Phalarope (supplemented by the Blue Wing) during the second and third 

 seasons. Owing, however, to an accident which prevented the use of the Phalarope 

 along the western shore of Buzzards Bay in 1905, the latter region was not dredged 

 until the summer of 1907. These 1907 stations have been charted along with the others 

 and the records included in the same series. There are likewise included with the regu- 

 lar series certain repeated stations. Owing to the somewhat tentative character of 

 the Vineyard Sound dredgings in 1903, 34 of these earlier stations were redredged (ap- 

 proximately) in 1904, partly with the Fish Hawk, partly with the Phalarope. Such 

 stations have been designated by the original number, with the addition of the Latin 

 word "bis." The "bis" stations have all been treated as Fish Hawk stations, and a 

 list of them is published at the end of the Fish Hawk series. The records for the occur- 

 rence of each species at this group of repeated stations have been incorporated serially
